Currently on its 45th anniversary tour, the Alvin Ailey American Dance Theater stops for six performances at the Auditorium Theatre through May 23. The program offers the Chicago premiere of Juba, choreographed by Robert Battle, and Alonzo King’s Heart Song, plus a number of company repertory favorites choreographed by Ailey himself, or by Judith Jamison, the troupe’s current artistic director. This troupe’s multi-cultural approach to contemporary ballet always has been energetic and unique. (312) 902-1500 (Ticketmaster); $22-$57.
